v To aZZ whom it` may concern:

supporting the lower extremities of invalids l when lying down, inwhich, by means of actuating mechanism two support frames larranged on astand and movable in relation to one another` are adjusted in position,and as required for the support at any time of the lower extremitieswithout altering the position of the invalid. Y y

One example of the invention is illustrated in the accompanying drawing.

' Figure 1 is a side elevation of the device.

Fig. 3 a view of the supportsfor the sup- Ip1ort frames, and Fig. 4 a side elevation of The frames 3and 4: which are movable in relation to one another about hinges 2 areconnected with the stand 1 by hinges 5. The bearings 6 are` rmlyconnected with the stand 1 and serve for the reception of the spindles 7that are provided with left and right screw-threads, carrying traversingnuts 8. The nuts have notches for the reception of the supports 9 whichare pivotally connected to the nuts by the stud screws 10. The otherends ofthe supports 9 are pivotally connected` by means of the studscrews 12 yto `the bearings 11, which are fixed on the frames 3 and 4:.

follows: By means of the crank handle 13 the spindles 7 are rotated, andin conse- ,quence of their being provided with right and left`screw-threads, traverse the nuts 8 on these `spindles toward or apartfrom one another, and vary the positions of the linked supports 9, sothat the frames 3 and 4. are lowered or raised, and at any time suitablyto the lower extremities to be supported. V'Ihe alteration in thepositions can be effected at any time without lifting the supportedextremities, soA that no pain is caused to the invalid. The movement ofthe one or the other frame is suiiicient for considerably affecting `theposition of the other frame, whereby the desired placing or supportingof the lower ,extremities` is What I claim and desire to secure byLetters Patent is n An article of the class described comprising twohinged sections, a base support hinged to one of said sections, bearingson the base support, a pair ofscrew spindles with right and left handthreads mounted in said bearings, a pair of traveling nuts mounted totraverse, on each spindle, links pivotally connected with the nuts andwith the hinged sections and means for rotating the spindlesindependently to eiTect the adjustment ofthe hinged sections,substantially as described.

In testimony whereof I have afxed my signature, in presence of twowitnesses.
